Server ECC RDIMM 16GB
This 16GB DDR4 module runs at 2666MHz with CL19 latency and 1.2V power. It is a registered ECC RDIMM built for servers, workstations and NAS systems that require error-correcting registered memory. The dual-rank 2Rx8 design fits 288-pin DDR4 slots. It will not work in standard desktop computers or alongside unbuffered modules.
Thermals and power at 1.2V
Operating at the standard DDR4 voltage of 1.2V keeps power draw low and heat output minimal in typical server workloads. The module has no heat spreader, relying on chassis airflow for cooling. Registered buffering adds slight electrical load but reduces signal stress on the memory controller during normal operation.
Sustained load behaviour
Under continuous use the registered design maintains signal integrity across all ranks, while ECC corrects single-bit errors without halting the system. Backward compatibility with 2133MHz and 2400MHz buses allows stable operation if the platform downclocks the module. JEDEC compliance ensures consistent timing at rated speed during extended sessions.

Spørgsmål om denne vare
How do I install the 288-Pin DDR4 ECC RDIMM and what step is often missed?
Align the notch on the 288-pin module with the slot key, press down evenly until both retention clips click, and verify the system runs at 2666MHz rather than falling back to 2133MHz or 2400MHz.
What maintenance or replacement will the 16GB 2Rx8 registered module need later?
No routine maintenance is required; if a memory error appears, replace the faulty 16GB RDIMM with an identical 2Rx8 CL19 1.2V module to keep ECC registered operation intact.
What limit appears first when the CL19 1.2V RDIMM runs under sustained load?
The registered buffer adds one cycle of latency, so the CL19 timing at 2666MHz becomes the throughput ceiling before voltage or thermal limits are reached.
